WINDIVIILL.

SPECIFICATION forming part of Letters Patent No. 427,100, dated May 6, 1890.

Application tiled August 31, 1889. Serial No. 322,517. (No model.)

To @ZZ whom it may concern:

Be it known that I, FLORY MILLER, a citizen of the United States, residing at Napoleon, in the county of Henry and State of Ohio, have invented certain new and useful Improvements in lVindmills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invent-ion relates to improvements in windmills; and it has for its object, first, to

provide means whereby the spindle which sustains the weight and strain of the wheel and is subject to the greatest wear can be economically replaced when worn; second, to provide an improved turn-table for reducing the wear on the parts to a minimum and for enabling the wheel to `turn with great ease, and, finally, to simplify the construction and make. the parts stronger and more durable.

Vith these ends in view, and such others as pertain to my invention, it consists of a horizontal rigid spindle which supports the vertical wheel, and which is carried by the horizontally-turning tubular casting or body of the mill, said spindle being made in two longitudinal separable sections which are firmly xed on the vertical tubular casting. In practice the lower section or member of the horizontal spindle is made integral with the vertical tubular casting, while the upper member of the spindle is connected to the lower member by a lap-joint and bolted at its inner end to the vertical tubular casting, the spindle being cylindrical in shape to adapt the wheel to turn thereon, as required. By making the spindle in two separate sections or members the upper member thereof, which sustains the greater wear, can be easily removed and replaced at a very small expense.

My invention further consists in the peculiar construction and combination of parts, as will be hereinafter more fully described and claimed.

In the accompanying drawings, Figure l. is a side elevation of my improved windmill. Fig. 2 is a vertical longitudinal sectional view thereof, and Fig. 3 is a detail transverse secsponding parts in all the figures of the drawings, in which- 1 designates the vertical casting, which is made hollow to permit a vertical tubular mast 2 to be fitted therein. The base of this casting is enlarged or flanged, as at 3,-and it rests on a series of friction wheels or rollers 4, which are journaled on shafts or pins 5, that are secured in a turn-table or annular bearing G, said bearing having a central circular boss 7 through which passes the mast 2. This tubular mast or post is fixed at its lower end tothe usual crown of the ordinary tower or dei-rick, and around said mast or post is fitted the annular bearing G, which bearing may be firmly clamped to said mast by means of set-screws 8, which work in threaded apertures in the bearing and bind against the mast. The tubular mast 2 serves to connect the vertical hollow standard to the tower and prevents the windmill from being carried away in a storm, and the annular bearing, with its friction wheels or rolls, serves to reduce the friction between the crown of the tower or derrick and the vertical standard 1, and enables the latter to turn freely in any horizontal direction.

At the upper end of the vertical hollow standard I have provided a rigidlbracket l0, having a central bearing 11 for the upper eX- tremity'of a tubular shaft 12, which serves to transmit the power to the pump or other machine at the base of the tower to be operated by 'the mill. This tubular shaft has secured to its upper end the driving-pinion 13, which meshes with a vertical master-gear 14, that is arranged at one side of the tubular hollow standard 1. This master-gear has a series of radial integral spokes 15, to which the radial spokes 35 of the wheel 3G are fitted laterally and secured by means of throughbolts, the wheel being built up on the mastergear, which is thus rigidly secured to the wheel, so as to rotate therewith and drive the pinion 13. This master-gear is fitted on a tubular horizontal shaft 16, which in turn is fitted on a rigid horizontal spindle 17, which is carried by the vertical standard 1, and projects outwardly at right angles therefrom. The tubular horizontal shaft 16 has an annular flange 18, that serves to confine the mastergear against lateral play on the tubular hori- IOC zontal shaft, and at its outer extremity said shaft is flared or enlarged to providea mouth 19, in which is fitted a nut 20, that serves t0 prevent endwise playof the tubular hollow vshaft on the rigid spindle, said nut being iitted on the outer end of the spindle, and is detachably held in place on the spindle by a transverse pin 2l, that passes through suitable apertures in the nut and spindle.

The wind-wheel 3G may be of any preferred construction, and it has a series of brace-rods 37,Which extend from the radial spokes 35 of the wheel to the enlarged outer end or mouth 19 of the tubular horizontal shaft 16, said brace-rods being rigidly secured to the spokes of the wheel and the hollow shaft, so that the wheel, the master-gear, and the tubular horizontal shaft all rotate or turn together. This cylindrical spindle is made in two longitudinal parts or sections 22 22', the lower one of which is cast integral with the Vertical tubular standard, and the other of which is detachably connected to the integral section by a lap-joint, the inner end of the upper removable section or part being provided with a lateral flange 23, which fits against a corresponding flange 23, made integral with the standard and the lower section or member of the spindle, and through the flanges are passed bolts 23', one of which is shown in Fig. 2, whereby the upper section of the spindle is removably secured to the lower section of said spindle and to the standard. By making the spindle in two parts one part can be removed when it has become worn by the weight and friction of the wheel, and replaced by another part at a small expense.

On the opposite side of the vertical tubular standard from the master-gear are cast integral lugs 24, in which is fitted a vertical shaft 25, that forms the pivot of` the bracket or casting 2G of the vane or tail, said bracket being fitted between the lugs, as shown in Fig. 2. The casting has longitudinal sockets 27 on one face thereof, in which sockets are received and secured the two longitudinal bars 27 of the vane or tail, (not shown,) and at its lower edge said casting or bracket is provided with a depending lug 28, which is adapted to impinge against a rigid horizontal arm 29, cast integral with the base of thevertical tubular standard, the lug serving to limit the play of the vane in one direction. On the outer end of this rigid horizontal arm is fitted a lever 30, the inner end of which is connected to the vane-castin g by a lilik or rod 3l, that passes through au eye 32 on said vanecasting. This lever is further provided with an adjustable regulating-weight 34, whereby the vane can be controlled, so as to be thrown out of the wind when the latter exceeds a certain pressure, and to the outer end of the lever is connected a cord or chain 40, which runs over a guide-pulley Ltl,that is journaled in the extreme upper end of the bracket on the vertical tubular casting 1, said cord or chain extending thence to the ground, so that the lever can be operated at will.

The operation and advantages of my invention will be readily understood by those skilled in the art to which it relates from theV foregoing description, taken in connection with the drawings.

Having thus fully described my invention, what I claim as new, and desire to protect by Letters Patent, is-

1. In a windmill, the combination of avertical standard, a horizontal cylindrical spindle having its lower section made integral with the standard and its upper section detachably secured to the standard and connected to the integral lower section by a lapjoint, a tubular shaft fitted on the cylindrical spindle and having its outer end provided with an enlarged hollow boss, a nut arranged within the boss-and fitted on the spindle to bear against the outer end of the tubular shaft, a master-gear carried by a tubular shaft and having a wheel erected thereon, and a driving-pinion which meshes with the master-gear, substantially as described.

2. In a windmill having a vertical standard, the horizontal spindle consisting of two semicylindrical members, one of which is made integral with said standard and the other section detachably secured to the standard, as and for the purpose described.

3. In a windmill, avertical standard l and the horizontal spindle consisting of two semicylindrical members which are united to each other by a lap-joint formed in the opposing faces thereof, the lower section of the spindle being made integral with the standard, and the upper section thereof being detachably secured at its inner end to the standard, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FLORY MILLER.
